Removed nbnxn kernel blendv optimization
The nbnxn simd kernel blendv optmization, which was accidentally
deactivated since 5.0, has been removed. It made assumptions about
the internal storage of SIMD representations. With gcc 4.x blendv
would give a small performance improvement, but with gcc 5 performance
is equal or deteriorates.
